Every year, millions of homes are sold in the US. In 2020 alone, people purchased over 5.5 million existing homes. One of the first priorities for many buyers once they close on those homes is renovating.
Renovations often focus on areas like kitchens and bathrooms. Yet, sometimes, you need practical improvements like a new HVAC system. In other cases, you move in knowing that the HVAC system will need a replacement within a few years.
Once you start shopping around, you’ll quickly discover that there are several types of HVAC systems in common use. If you’re not clear on the differences, keep reading for our quick guide to these systems.
Split Systems
Of the systems the HVAC industry has to offer, the common one you’ll see in most homes is a split system. A split system employs two separate units, one inside and one outside.
The inside unit is the furnace. The outside component is an air conditioning unit. A blower distributes the heated or cooled air through a duct system.
While these are the most affordable systems, an unexpected replacement can still prove a financial strain. You’ll want to look for an equipment provider that offers flexible financing.
Ductless Split Systems
A popular option for homes without a duct system is the ductless split system. These systems typically use an outdoor heat pump unit. Inside the home, you get up to around 4 individual units that distribute the heated or cooled air.
You can think of this as smart HVAC because each unit employs its own thermostat, so you can adjust temperatures in specific rooms or zones. While installation typically proves less work-intensive than a split system, you’ll still want a local HVAC company for the job.
Packaged Systems
While an option for homes, packaged systems are comparatively rare. Instead of using a separate furnace and AC unit, the packaged system packs all of the components into one unit.
As a general rule, these systems are installed outside the home. Exposure to the elements increases the wear and tear on the unit, which means they’re not the best HVAC system option in most cases.
Geothermal Systems
Geothermal systems also use a heat pump, but they rely on pipes buried under the ground for primary heat exchange. In the summer, the liquid in the pipes sheds heat into the comparatively cooler ground. In the winter, the liquid absorbs heat from the comparatively warmer ground.
These systems are often quite expensive compared with other options.
Choosing Between Types of HVAC Systems
Choosing between types of HVAC systems depends on several factors. Practicality plays a role, since replacing a split system with another split system involves less work. A ductless split system can make more sense if your home lacks ductwork.
Budget plays a role as well, as split systems are often the cheapest option for upfront costs. Long-term cost efficiency is a different story, as both ductless systems and geothermal systems cost less to run over time.
